According to Feldman, "this affair points to far more severe
failures than the ones committed by the defense establishment in
Zygier's case. Regarding Zygier's case, the authorities that
recruited him didn't understand who they were dealing with and
weren't aware of his conduct. Okay - that's a failure. Prisoner X
number two is an entirely different story - a horrible security
breach. When I heard the story, as an Israeli citizen I was
shocked, and the subject was completely silenced by lawyers who
enjoy close ties with the establishment. Whoever opens this
affair will be doing the country a great service."

Earlier Tuesday, Feldman compared the two cases on Army
Radio: "One: they’re both Israelis. Two: They worked for a
security agency of the highest level of secrecy. Three — and this
is important — their activity points to a security failure that
allowed the crime to be committed, secrets to be kept, or other
deeds to be done,” Feldman said on “Boker Tov Yisrael” (Good
morning Israel).

The second prisoner is referred to in documents only as "the
other inmate of Block 13."
